Title: Phase servo device
Inventor: MAKUTA HIROYUKI
IPC: H02P29/00
Filed: 1988-08-10
Abstract: PURPOSE:To control a motor driver circuit so that the value of phase difference is brought to a specified value close to zero by outputting  t as phase difference when the arrival time difference  t of reference pulses and servo pulses is brought to T1/2 (T1: the period of reference pulses) or less and ( t-T1) as phase difference when  t is brought to T1/2 or more. CONSTITUTION:A phase comparison processing section 17 subtracts the arrival time tr of reference pulses from the arrival time tp of speed servo pulses, and obtains time difference  t. Time difference  t and T1/2 (T1 represents the period of reference pulses) are compared, and ( t-T1/2) is output as a phase difference signal when  t>=1/2 holds and  t as a phase difference signal when  <T1/2 holds. A motor driver circuit is controlled by an error Ep between the phase difference signal and aimed phase difference. Accordingly, the value of the phase difference of servo pulses and reference pulses can be controlled so as to be brought to a specified value close to zero.

Title: Photoconductor
Inventor: TAKASAKI KANETAKE
IPC: H01L31/09
Filed: 1988-08-12
Abstract: PURPOSE:To reduce a dark current, to provide high sensitivity and spectral sensitivity near that of human eye and to reduce an after-image by forming it of an amorphous silicon having specific amount or less of carbon atom content. CONSTITUTION:An amorphous silicon photodiode is formed by sequentially laminating a chromium electrode film 32, an amorphous silicon film 33, and an ITO film 34 on an insulating board 31. The film 33 is formed of amorphous silicon having 1X10<18> pieces/cm<3> or less of carbon atom content. The content of the carbon in the silicon affects an after image. Accordingly, when a photodiode is formed of the amorphous silicon having 1X10<18> pieces/cm<3> of the quantity of contained carbon, the after-image becomes 1% or less. Thus, a dark current is reduced, sensitivity is satisfactory, spectral sensitivity is near that of a human eye, and the after-image is decreased.

Title: Method for controlling surface roughness of strip
Inventor: NAGASAWA TETSUO
IPC: B21B37/00
Filed: 1983-10-27
Abstract: PURPOSE:To control optionally the surface roughness of a strip at a low cost without exchanging work rolls by winding a strip on the work rolls rotating at different circumferential speeds and rolling the strip under the rolling load changed within a specified range of elongation percentage. CONSTITUTION:Rolling load is changed within the range where elongation percentage is maintained constant with respect to the rolling load in a perfect PV state with a PV-E rolling mill which performs temper rolling of a strip by winding the strip on a pair of work rolls rotating at different circumferential speeds. If the rolling load is increased, the surface of the work rolls is rubbed with the surface of the strip, by which the strip is finished to the smooth surface. Conversely when the rolling load is decreased, the influence of the surface roughness of the work rolls on the surface of the strip is decreased and the strip is finished to the rough surface. The surface roughness of the strip is controlled as desired by adjusting the rolling load according to the above-mentioned method.

Abstract: PURPOSE:To produce a thermoplastic resin sheet which sharply reduces and prevents the occurrence of warp due to moisture absorption, by a method wherein opposite ends of a resin sheet continuously produced at a producing time of a thermoplastic resin sheet are previously set to a size being slightly shorter than that of the center part. CONSTITUTION:A thermoplastic resin sheet, i.e., methacrylic resin, is fed to rolls 3 in which the center part is different in a surface temperature from the opposite ends, the surface temperature being higher than a temperature which is 15 deg.C lower than a heat distortion temperature of a resin sheet material, and the center part of said resin sheet is pushed upward and downward.

Referring to a drawing, the resin plate 1 extruded from an extruder passes through the rolls 3 via a polishing roll group 10 and is conveyed by carrier rolls 2. The sectional shape, in a direction of width, of the roll 3 is shown in 33, and the center diameter is slightly larger than those of the opposite ends. The roll 6 is that which has no change in a diameter in a direction of width.

Title: Semiconductor device
Inventor: YOSHIHARA KAZUHIRO
IPC: H04L7/08
Filed: 1999-07-15
Abstract: PROBLEM TO BE SOLVED: To eliminate the need of a circuit for shifting a channel so as to be adjusted to the channel order of a transmission side and to prevent the increase of power consumption due to the increase of a logic scale and to prevent the lowering of yield due to the increase of a chip area by outputting star bits showing the head of the multiplexed channels in parallel. SOLUTION: A circuit multiplexes the signals of four channels and transmits them. A star bit is outputted in synchronizing with a channel 1 (D1) being the head channel of the signal of four channels. It can be judged at which timing the head channel is multiplexed by using the star bit signal (SB) to the reset signal of a reception side and the channel of a transmission side can be adjusted to the channel of the reception side. In the circuit multiplexing the signals of four channels, a signal where 1/4 of one period becomes high and 3/4 becomes low can be generated. Thus, a circuit shifting the channel so as to be adjusted to the channel order of the transmission side is unnecessitated.

Filed: 1988-08-12
Abstract: PURPOSE:To execute judgement of aging without growing size by calculating a resistance portion current containing a high frequency component from a sampling data train to compare a peak value thereof with a reference value. CONSTITUTION:A monitor 11 for an arrester 10 has a sampling means 5 and an arithmetic device 6.

Then, the device 6 subtracts a capacity portion current from the current of the arrester 10 by a resistance portion current calculating means to calculate a resistance portion current. Moreover, a peak value containing a high frequency portion is calculated by a peak value calculating means from the numeral values thus obtained. Then, an aging judging means compares a peak value of the resistance portion current with a reference value, thereby enabling accurate judgement of aging of the arrester 10 corresponding to the system voltage.

Title: State monitoring system for base station in communication system
Inventor: TABATA SHUICHI
IPC: H04W24/10
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To dispense with the individual path-settings and to improve cost performance by monitoring the states of plural base stations in a tone idle state and using a common speech channel to perform both calling and transmission. SOLUTION: When base station call monitoring devices 3-1 to 3-n are decided to be in tone idle states, these monitoring devices send the signals to a call- monitoring device 1 of a central device 4 to indicate the tone idle states. Receiving these signals, the device 1 counts the time via its built-in timer, after a fixed time has passed after the reception of signals or if a silent state lasts for a fixed time. Thus, the device 1 detects a silent state and decides a tone idle state to send the tone idle information to a state-monitoring controller 2. Then the controller 2 sends the state-monitoring signals to the base stations 5-1 to 5-n via a speech channel. Receiving the state monitoring signal, every base station sends the state-monitoring data to the controller 2 of the device 4.
